Poor circulation of the lower limbs
For the normal functioning every human body needs oxygen. He goes to the organs and tissues from the blood. Consequently, in order to function properly the body must complete circulation.
In violation of the structure or function of the arteries or veins of the legs there is poor circulation of the lower limbs.
Causes of circulatory disorders of the lower extremities
The main causes of circulatory disorders can be divided into 2 groups: the arterial and venous.
1. varicose veins.
Vienna do not have the muscle wall, so can not be reduced. However, the blood, overcoming the natural power of the earth's gravity, to strive upwards towards the heart. This is due to many factors. One of them is the presence of communication (connection) veins of special valves. They do not allow the reverse flow of blood from the superficial to deep veins. From deep vein blood rises above for the following reasons:
- The blood pressure of the arteries.
- The work the leg muscles. Muscles, figuratively speaking, acts as a pump, clenching and unclenching. With the reduction, they push blood from the deep veins. When muscle relaxation movement is supported only by the pressure of the blood from the arteries.
- The presence of valvular apparatus.
Under adverse conditions, the veins may become less elastic, valves atrophied, and there is varicose veins and then, as a symptom, a violation of venous circulation of the lower limbs.
The causes of varicose veins are many: bipedalism, genetic predisposition, hormonal disorders, diseases of the nervous system. The important role played by lifestyle, low mobility, sedentary or standing work long stay in one position.
Thrombophlebitis called inflammation of the vein wall altered in the presence of her blood clot. Therefore, the disease in some cases is a complication of varicose veins of the lower extremities.
Inflammation thrombophlebitis is aseptic, ie proceeds without microbes.
Most often, patients with thrombophlebitis already have quite a serious illness, leading to circulatory problems of the lower extremities and thrombophlebitis. These are patients with chronic heart failure, severe endocrine problems, cancer, etc.
Depending on the size of a vein thrombus can be closed completely or partially. Partial closure of the lumen of the vein leads to the formation of chronic venous circulatory disorders of the lower extremities.
Diseases of the arteries, leading to poor circulation of the lower limbs:
1. obliterating atherosclerosis of the main vessels of the lower extremities. This disease affects mostly men over 40-45 years. Obliterating atherosclerosis - a disease of chronic, long-flowing and leads to severe impairment of blood flow. Most affected artery average (popliteal, femoral) and large caliber.
Arteriosclerosis obliterans is a manifestation of systemic atherosclerosis. In this disease localized changes in the intima of arteries. It postponed cholesterol and fatty plaques formed. At the initial stage of this process is reversible. Vessel lumen narrowing, and gradually begin to show signs of circulatory disorders of the lower extremities. As the plaque is compounded and circulatory disorders clinic.
From major atherosclerotic plaque may eventually already been set up and the pieces fall into the underlying artery. Since they have a smaller diameter, the clot can get stuck, cause acute failure of blood supply and cause gangrene.
2. occlusive disease (thromboangiitis) - is a chronic systemic inflammatory disease that affects the small arteries of the lower extremities. Until now, the exact cause of the disease has not been established. There are several basic theories of obliterating endarteritis:
- infectious and toxic (provocateur - the infectious agent);
- pathology of blood coagulation;
- allergic (allergic reaction to tobacco);
3. Diabetic angiopathy. Diabetes is a risk factor for cardiovascular disease. Defeat may have the character of the macro- or microvascular complications. Over time, poor circulation of the lower extremities leads to necrosis of the most remote areas: toes, then lower leg, etc. Aggravates diabetic angiopathy fact that patients in this group only in rare cases are not related obliterating atherosclerosis or cardiovascular disease. In most cases, there is a combined pathology, and, consequently, poor circulation is progressing fast enough.
Risk Factors leading to the development of lower limb circulatory disorders
- Increase the level of cholesterol and lipid balance of the violation;
- High blood pressure;
- Increase the level of homocysteine;
- Obesity 1 or more degrees;
- Sedentary lifestyle, etc.
The main symptoms depend on the degree of circulatory disorders.
In the initial stages the patient may be concerned about mild discomfort or pain after a relatively short exercise. As the progression of disorders in the circulation of the lower limbs symptoms become more pronounced. The pain intensified, there is a characteristic symptom - intermittent claudication. It refers to a pronounced pain or discomfort in the legs that occurs with walking and disappears when you stop. Judging by how far people can go before the emergence of intermittent claudication, determine the degree of circulatory disorders.
As the progression of disorders occur trophism skin: they are pale, dry, sores can appear. In advanced process begins gangrene.
Treatment of circulatory disorders of the lower extremities
Single regimens circulatory disorders not. This is due to the fact that the diagnosis itself: "poor circulation of the lower limbs" no. This symptom, which is a sign of the disease.
If the violation of venous circulation of the lower limbs caused by varicose veins, then it should be treated exactly.
If the cause - atherosclerosis, it is always necessary to adjust the diet to normalize the levels of total cholesterol and other lipids.
In addition to specialized treatment always have general guidelines, following which can slow the progression of circulatory disorders of the lower extremities. First of all - this is not smoking. It also includes maintenance of the mobile lifestyle. The risk of developing cardiovascular disease increases dramatically if a person goes through a week of less than 12km.
In the complex treatment of circulatory disorders of the lower limbs always includes physical therapy and physiotherapy.
